Gregarious. Appears to be active either at night or during the day. Seeks shelter under dead wood and is capable of intestinal breathing (Ref. 35381). Commonly occurs in the lower reaches of large rivers. Known to feed on fruits, thus helping to scatter several plant seeds. Also feeds on small fishes and insects and often manifests the behavior of a detritivore (Ref. 27188). Probably migrate upstream during reproduction. The female lays an average of 50,000 eggs which are fertilized externally (Ref. 35381).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00742 - 0.01120), b=3.04 (2.98 - 3.10), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.43 se; based on food items.
Generation time: 2.3 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
